The AFI of ROAIPAddress (defined in 3. The ROA eContent of

For which reason is it necessary to have a variable AFI size? We are
having just two values 0001 and 0002 and it is unlikely to see new
address families at a count that exceeds 2^16. So why should there
be a third byte?

RFC 2858 defines AFI as 2 bytes, and the optional SAFI as one more byte.
That's why RFC 3779 defines a 2-3 byte data element for this pair. The ROA
syntax inherits that structure.
